COutputQueue::Receive (Compact 2013)

3/26/2014

Passes in a single sample to send to the input pin.

Syntax

HRESULT Receive(
  IMediaSample* pSample 
);

Parameters

  • pSample
    Pointer to the sample to be passed to the connected input pin.

Return Value

Returns an HRESULT value, which can include the following values, or others.

Value

Description

S_FALSE

End of stream detected before or while processing sample; any further samples will be discarded and this value returned.

Other

An error occurred before or while processing sample; any further samples will be discarded and this value returned.

S_OK

Queued successfully or passed to the connected input pin if there is no queue.

Remarks

If the sticky return code (m_hr) is not S_OK, the sample is not sent and the sticky return code is returned. (A sticky return code is one that persists even after operations that would usually change its value.)

The samples are all released (by means of Release) after processing, regardless of whether the processing was successful.
